STRIPING MACHINE.

To all whom t mag/,concern Be it known that I, HRANT Gr. AN'rARA'- MIAN, a citizen of the United States, resid. Y

a series ot horizontal pulleys, 5, four such ing at Kenosha, county of Kenosha, State of Wisconsin, have invented a certain new and useful Improvement in Striping ,Mw chines, and declare' the following to be a full, clear, and exact description of the same, such as will enable others skillediin the art to which it pertains to make `and use the same, reference being had to the accompany` ing drawings, which form a 'part' of this specilication. l y y e My invention has for itsobject to produce a simple and novel machine for forming stripes or bandsaccurately and expeditious ly on rods, tubes or the like. l i rl`he various features of novelty whereby my invention is characterized will hereinafter be pointedv out with particularity in the claims; but, for a full understanding of my invention andof its objectand advantages, reference may be had tothe following detailed description taken vin connection with thev accompanying drawings, wherein: c

Figure 1 is a side elevation 'of a machine constructed in accordance with apreferred form ol my invention;

Fig. 2 is a section taken approximately on line 22 of Fig. l; f

Fig. 3 is a line 3-3 of Fig. 1; l

Fig. 4 is a vertical section onan enlarged scale through the lower partof the machine adjacent to the manual controller for the machine; 4

Fig. 5 is a plan view of the automatic stop device for the rotating carrier;

Fig. 6 is a vertical sectiontbrough one of the upper worlcsupports, on an enlarged scale; Y

Fig. 7 is a side elevation oty one of the lower rotatable work supports and a'fragk ment of the stop mechanism shown in Fig. 55and Fig. 8 is a modified form of lower work support adapted to grasp the exterior of a rod or tube. l

Referring to the drawings, l "represents a horizontalr flat base above which is ahorizontal ring-like plate, 2,, having a section removed therefrom on the front side. Bef tween the members land 2 is a horizontal table, 3, whichvmay convenientlyftakethe form of two parallel sp'oked wheels fastened together. 'The members 3 `.is fixed to a revsection taken approximately on Specification of Letters Patent. Patgntgd `Aug. 8, 1'922, y Application led September 9, 1920.` Serial No. 409,119.

`oluble vertical rod, 4l. yAs vbestishown in Fig. 2, there are revolubly mounted at reg` ular intervals on the under side of the table 5, may conveniently be held against vertical displacementby locating them between the upper and lower halves of the rotatable table. The axle, 11, of each ofthese latter i` rpulleys proiectsldownwardly through and below the lower half of the table and upwardly through the upper half; the upper end'being provided with a suitable holderl`or the lower end olf-a rod orv a tube. holdermay take the form of a steep pyramid as shown at 12 inFig.' 7, so as to enter the lower end of a piece of work in the form of a tube and bite into it sufficiently to make the work turn lwith the pulley. which the holder may take is shown in "Fig, 8, the holder inY this instance being in the formof aconical socket, 13, having sharp internal ribs or projections, 14, which will grip vthe bottom exterior edge of a tube or the bottom edge ot a rod ,and clutch the same to the pulley.

On the upper end oit the rod, 4, is an upper work-supportingplate, 15, slidable ver- The i' Another form ci' tically on` the rod but heldagainst rotation relatively thereto by meansot a key, 16` extending lengthwise of the rod or otherwise. The member 15 has a series or work-engaging members each lying directly abovey one ofthe lower work-holders, the upper mem- `bers being adapted toleep tubes or rods in vertical bearing, 19, carried `by the part 15,

the pin having on-`its lower end a conical head, 20. A spring, 21, in a chamber in the i" bearing 19 holds the pin down but permits it to 'bey raised in placing a piece of work in position ortaking' it out of the machine.

The member .15 may be raised and lowered team] wheel becomes a4 crank which oscillates the' corresponding postwhen ythe wheel'is ro,- tated. The effective length of the arms50 may be adjusted in any suitable way., con! from the pivot 55, of the swinging member` so that, whenever. the post isA oscillated,..it produces a similar oscillation inthe corresponding member 30.

It is necessary 'that the rotating wor carrying table be always brought to rest with the pieces of work in operatives relation to those portions of the abrading strip threaded through the swinging members 30. I have therefore provided the automatic stop which is best shown'in Figs. 3 and 5; lThe stop comprises a horizontallyswinging` Zshaped lever, 56, supported from the base by a pivot or bearing, 57, arranged at about the middle of the lever. together with ak bar, 58,-con nected at its middle to thefront vend of the lever 56 by means of a link, 59, and connected at its rear end to fthe rear end of the lever 56 hy a link. 60. A spring, 61, between the members 56 and 58 tends to spread them apart as far as the links will permit. 0n the front end of the bar. 58, is an upward projection, 62. which normally lies in theipaths ofthe lower ends of the axles of the lowermost work holders as best shown in Figs. 5 and 7. Therefore, whenever the table isfrotated in the clockwise direction as viewed. in Figs. 2 and 3. it travels until one of the axles. 11,

' strikes against the projection 62 and the rotation of the table will then cease. In order to release the table so as to permit it 'to continue its rotation I have placed on the toothed wheel. 41. on the vertical shaft. 4, a suitable part which, once during each revolution of the wheel 41'` will engage with the adjacent end ofthe lever 56 andfswing the stop mechanism from the positionbillustrat# ed in full lines in Figs. 3 and 5to the posi* r for the worm shaft, The rotation of the table is always in the clockwise direction as viewed in Fig. 2 and, 4by causing the belt 6 to run in this same direction, the belt will tend to rotate the table when free to do so. Furthermore, by causing the weight of the loadedtable to rest upon the toothed wheel 41, a frictional driving connection is secured be tween v`this wheeland the table which will cause the table to rotate slowly whenever it is free to do so. This frictional driving con nection may conveniently be accomplished by fixing on the lower end of the vertical shaftj4 suitable collar, 63, resting on the toothed wheel 41. This collar may conveniently bein the form of a ratchet wheel engaged by a spring-pressed pawl, 64, carried by the wheel 41. The pawl is set in such a way that the wheel 41 may move independently of the vertical shaft in the direction in which the worm shaft tends to drive the wheel, but it prevents backward movement of the table and alsor acts in the manner of a brake. The pawl may conveniently be used as the part carried by the wheel 41 for engagement with the lever 56 of the stop device. f f

The operation of the machz'ne.-Assiiming that single band or stripe is to be produced on a lot of tubes of the same length, the top plate, 15, of the) machine is raised .high enough' to permit four of the tubesto be set into the machine as heretofore described;

three of the pieces of work being in operativel relation to the swinging strip-carrying arms, 30, and the fourth being in an idle position aty the front of the machine. `The main driving shaft is started and the clutch controller, 37, is depressed, causing the worm shaft to revolve. As soon as the main shaft begins to revolve, the belt, 6, rapidly rotates the three pieces of work which are in operative relation to the abrading strip, so that the surfaces thereof are worn to produce on each a band or stripe. This continues during about the time it takes the group of gear wheels 41, 42, 44, 45 and 47 to make onequarter of a revolution. The gear wheels 42. 44 and 45 then reach such positions that they begin swinging the posts, 49, in a direction to carry the..swinging strip-carrying arms outwardly away fromzthe work. When the strip has been carried clear of the work it will be found that the pawl, 64, has reached a position to cause the rotatable table to be released from its stopso that the table will begin to revolve and will not again come to rest' until it has 'traveled through an angle of ninety degrees, at which point the-piece of work which is at the right in Fig. 2 will have been carried to the front of the machine. By the time the table has completed its quarter turn the swinging strip-carrying arms` will have started to travel inwardly so as to bring the strip into roperative relation to the three pieces of work in working positions. The inward swinging of the arms, 30, is completed shortly after the table has been brought to rest by its automatic stop device. The workman then removes the piece of work at the front of the machine and puts in a new piece. Of course, when the machine is first loaded, the table should be allowed to make a complete rotation before a piece of work is removed, in order to permit each piece to pass through its three working` positions. Thereafter, however, whenever the table stops, it presents a completed piece of work at the front side of the machine. It will be seen that each quarter f' turn of the table corresponds to a complete rotation of the gear wheels 4l, 42, 44, 45 and 47 so that after each quarter turn of the table the pin, 48, on the gear wheel 47 will s engage with the clutch lever, 35, and cause- 'i' the clutch between the main driving shaft and the worm shaft to be thrown out. Gonsequently, while three of the pieces of work may continue to rotate, the table cannot again start ahead until the operator presses down the manual clutch actuator, 37. lt will alsobe seen that whenever the worm shaft is running it is operating the feed rolls for the strip, so that the strip is slowly unwound from the spool.

Thile I have illustrated and described with particularity only a single preferred form of my invention, I do not desire to be limited to the eXact structural details thus illustrated and described; but intend to cover all forms and arrangements which come within the terms employed in the definitions of my invention constituting the appended claims.
